One of the ways Satan leads human beings astray is by
making evil look good.

On this point, ibn al-Qayyim wrote the following:

‘From his stratagem is that he always bewitches the mind
until he can deceive the person. No one is safe from his bewitching except
whomsoever Allâh wills. He makes good looking to him what harms him the most,
until he imagines that it is the most beneficial act for himself. And he makes
him flee from the most beneficial act until he thinks it is something harmful to
him. Certainly, there is no god but Allâh. How many humans have been tested by
such sorcery. How many hearts have been kept from Islâm, faith and goodness [by
such sorcery]. And how many support and present falsehood in the best form and
hate truth and present it in the worst form [because of his deception]. And how
much falseness is adorned and shown in a desirous manner to the alert. And how
much falseness is spread among the wise. He is the one who bewitches the mind
until it follows different desires and various evil opinions. He makes them
follow every path of misguidance. He leads them to actions, one after another,
that cause their destruction. He makes appealing to them the worship of idols,
the breaking of familial relationships, the killing of daughters, marrying
one’s mother and so on. And he promises them the victory of paradise with
their infidelity, wickedness and acts of disobedience. He presents to them
polytheism in the most honorable fashion. And he presents rejection of Allâh’s
attributes, of His transcendence and of His speech in the guise of
anti-anthropomorphism of Allâh. He presents abandoning ordering good and
eradicating evil in the guise of having mercy for others, behaving with others
in a good manner, and applying the verse, “O believers, you are in charge
of your own souls” (al-Mâ’idah: 105). And he presents turning away from
what has come from the Messenger in the guise of blindly following the Imams (taqleed)
and the sufficiency of following one who is more knowledgeable. And he presents
hypocrisy and compromising with respect to Allâh’s religion in the guise of
being flexible and mixing admirably with the people.’
